A solution containing 2 g of a non-volatile solute in 20 g of water boils at 373.52 K. The molecular mass of the solute is ___________ g mol−1. (Nearest integer)

Given, water boils at 373 K, Kb for water =0.52 K kg mol−1

Step-by-Step Verified Solution

ΔTb=Kb.m

(0.52) = (0.52) (m)

m=1=2(1000)(mw)(20)

mw = 100
